Are any of these sites working currently for youtube views since the youtube update?
I know U2B said they would be back up in afew days.
But I don't know about the other sites and I just don't wanna risk abunch of credits on something they might or might not have fixed yet.If you have a site that is not listed here and is working please do share.

Dunno for this list but SYV does the job for me.

what about linkcollider did you check to see if it's still working?
